During the enterprise data integration, the heterogeneous data source is mostly accessed through adapters. It is difficult and long to develop a specific source adapter. At the same time, configuration and deploy- ment of data integration system are complex due to the complex business system. This paper develops a business-oriented data integration system, which cannot only resolve the data integration between the heterogeneous source in Distributed Computing Environment，but also make the system's deployment and expansibility simple. It introduces the system's architecture, gives a development framework of source adapter and a method to data capture and sending. As a application case, a resoluble approach about some general merchandise group is also put forward.
